Designed and manufactured using the same high quality movements as our standard series Iris Diaphragms, the Zero Aperture series provides total light extinction. This type of control is often used in systems where the dark signal (background noise) must be measured for calibration. Two sets of leaves are used which are mounted on different tiers and are moved by one lever. For each iris, there are two additional relief leaves (not listed in table) that are not visible.
Note: Iris Diaphragm Mounts sold separately.
